To all who/wit may concern:

Be it known that I, S'rnrmine S'rnPHENs, a cltlzen of the United States,-res1d 1ng at State of Florida, have inventeda new and useful Auto-Rim, of which the following is a specification. iv

Thedevice forming the 'subj ect matter of this application is a rim, and the invention aims to provide novel means'whereby pneumatic elements subject to puncture and deterioration may be dispensed with.

Another object of the invention is to provide novel means for compressing a filler which is located within the tire casing.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the present invention appertains.

WVith the above and other objects in View which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodimentof the invention herein disclosed can be made within the scope of what is claimed, without departing from the spirit of the invention. 7

In the accompanying drawings Figure 1 shows in. cross section, a rim constructed in accordance with the present invention;

Fig. 2 is a cross section of the rim, parts being broken away;

Fig. 3 is a fragmental side elevation showing one of the rim forming members, the line 2-2 in Fig. 3 indicating approximately the cutting plane in which Fig. 2 is taken;

Fig. 4 is a side elevation showing the said rim forming member, the line 11 in Fig. 4 indicating approximately the cutting plane on which Fig. 1 is taken; and

Fig. 5 is a fragmental cross section showing a modified form of the invention.

In carrying out the present invention there is provided a pair of continuous a11- nular rim forming members 1 and 2. Ad-

. jacent their outer edges, the rim forming members 1 and 2 are equipped with circumscribing grooves 3 defining flanges 4 which may be turned over to form beads 5 adapted to prevent the rim-cutting of a casing 6, the edges 7 of which are received in the grooves 3. The casing 6 may be made out of PATENT] OFFICE.

rubber or a rubber compound, as is common in the art. The members 1 and 2 of the rim are spaced apart at their inner edges, as

shown at 8. The members 1 and 2 of the rim are provided with inclin'ed'iaces 9 which slant toward the'median plane 'ofthe rim and toward the center of rotation of the rim. The member 2 of therim'has cir 'c-umferentially spaced tongues '10. 5 There may be any number of these' tongues 110, but six of them will be found to besufficient under ordinary circumstances. The'memher 1 of the rim is provided withrecesses 11 in which the tongues 10 fit closely but slidably. In the member 1 of the rim are formed passages 12.- These passages are not threaded. In the member 2 of the rim are formed passages 14, the passages 14 being threaded. A screw 15 is journaled in each of the passages 6 and is threaded into each of the passages 14, the screw l5 having a head 16 which bears against the outer lateral edge of the rim member 1. There may be any number of the screws 15, but

six of them will prove ample. Located in-- side of the casing6 is a filler 20 which may be made outof cork, sponge rubber or any other suitable substance havingsome compressibility and resiliency.

By rotating the screws 15, the rim members 1 and 2 may be advancedtoward each other and then the slant faces 9-, engaging the filler 20, will compress the same in the casing 6. The tongues 10, being received in the recesses 11,prevent relative circumferential creeping movement between the rim members 1, and likewise'line upthe passages 12 and 14 in therespective rim members to receive the screws 15.

In the modification shown in Fig. 5, one rim member appears at 25 and its slant face is shown at 26. The casing is delineated at 27 The rim member 25 has in inwardly extended clencher flange 28 adapted to en- 'gage'a clencherbead29 on the casing 27.

Fig. 5 is introduced intothe drawings-for the'purpose of showing that the invention may be applied with satisfactory results,

irrespective of the means whereby the tire casing is connected with the members of the rim. v 7

It is to be observed that the recesses 11 extend part way through the member 1, to.

ported: The tongues fill the recesses 11 vbut partly,- thereby to leave the recesses open adjacent the slant face 90f the memher 1. As a consequence, when the screws 15 are tightened up, parts of the compressible filler will be forced into the open pore eons of the recesses ll; th'ereby to avoid a i creeping ofthevfiller.
